Michigan LLC name

If you file your Michigan LLC paperwork with a name that is already used by another company, or that doesn’t meet the Michigan name rules, your filing may be rejected.

The first step to checking if your LLC name passes, is to make sure your name is not already taken by another business.

You can do this using the Business Entity Database. And you need to do this because two businesses in the state can’t have the same name or be too similar.

The second step is to make sure your LLC name follows the state rules, which we’ve broken down below.

How do I search the Michigan business name database?

You can use the Business Entity Database to search your business name against the existing businesses registered in Michigan.

Note: The Business Entity Database is maintained by the Michigan Department of Licensing and Regulatory Affairs (LARA) in the Corporations Division.

Visit the Michigan Business Entity Search page:

Michigan Secretary of State: Business Entity Search

  1. Type your desired LLC name in the “Search by Entity Name” field.
  2. For the “Search type” dropdown menu, leave it on “Begins With”.

The Michigan LLC Entity Name search box is the first field on the LARA search page under Search by Entity Name.

Search tips:

  • Leave out “LLC”, “L.L.C.”, etc., when doing your searches.
  • Leave out any commas, periods, apostrophes, etc.
  • You can search using uppercase or lowercase letters.

How to interpret the Michigan business name search results

If the results show names that are not too similar to yours (meaning yours is distinguishable), then your LLC name is available for use.

  • Let’s keep using the example above. If your desired name is Riverwalk Studios LLC, and the only similar names you saw were “Riverwalk Study Agency” and “Riverwalk Studio Starters“, then your name should be available.

Michigan LLC Business Name Search Results include the entity name, ID number, Old ID number, and address.

If no results show up, that means your LLC name is unique and it should be available for use. To be safe, run your business name search again using only part of your LLC name (to double-check that there are no similar names).

  • For example, search just the word “Riverwalk” instead of Riverwalk Studios.

If your exact LLC name appears in the list, your LLC name is not available for use because another business is already using it.

If the results show a name that is very similar to yours, your LLC name may not be available for use.

  • If your desired name is Riverwalk Studios LLC, and the search results show a “Riverwalk Studio“, then your name is not available.

What if my desired LLC name isn’t available?

If your name is not unique, you’ll need to come up with a variation or a different LLC name.

Tip: Wait until your LLC is approved before you apply for your LLC EIN Number, reserve a domain name (web address), or purchase any other marketing materials. This way you don’t spend money on business supplies you can’t use because your business name isn’t available.

When in doubt, call the Secretary of State

We also recommend calling the Michigan Secretary of State to confirm that your LLC name is available.

Not all states offer this service, but the representatives in Michigan will tell you whether or not you can use your business name.

Their phone number is 517-241-6470. Their hours are Monday through Friday, from 8am to 5pm Eastern Time.

Michigan LLC name requirements

As per Section 450.4204 of the Michigan LLC Act, there are a few rules and requirements for naming Limited Liability Companies that you need to know.

Do I have to use a comma in my LLC name?

No, you don’t have to. You can file your LLC name with or without a comma. Both versions are accepted by the state.

For example: If your desired Michigan business name is Grandpa Joe’s, you can file it as:

  • Grandpa Joe’s LLC
  • Grandpa Joe’s, LLC

Or, instead of having “LLC” as your designator (ending), there are a few other options in Michigan.

What designators (endings) can I use in my LLC name?

Your Michigan LLC name must contain one of the following designators at the end:

  • LLC
  • L.L.C.
  • LC
  • L.C.
  • Limited Liability Company

The following designators are not allowed

Your Michigan LLC can’t make itself sound like a Michigan Corporation or any other legal entity besides an LLC.

The following words and designators can’t be used anywhere in your LLC name:

  • Inc.
  • Corp.
  • Corporation
  • Incorporated

What words are not allowed in my Michigan LLC name?

Your Michigan LLC name can’t contain words and abbreviations that are restricted by law.

For example, you can’t make your LLC name sound like it’s a bank, part of the government, or anything else that misleads the public.

You also can’t use words that are reserved for licensed professionals. These vary by state, but some common examples are accountants, architects, attorneys, dentists, and engineers.

For a full list of words restricted in Michigan, please see this page: Michigan Secretary of State: Restricted Words.

Your Michigan business name must be distinguishable (unique)

When you search the Business Entity Database, you will compare your desired LLC name to existing businesses in the state.

If your name is not unique, you’ll need to come up with a variation or a different business name.

Below are rules and examples of LLC names that are not distinguishable.


Differences in designators (endings) don’t create distinguishability.

If your desired LLC name is Apple Blossom LLC, it’s not available to use if any of the following are found in the database search results:

  • Apple Blossom, Inc.
  • Apple Blossom Corp.
  • Apple Blossom, L.L.C.

Filler words

Adding non-meaningful or filler words (the, a, an, and, &, of, or) won’t create distinguishability.

If your desired LLC name is Petoskey Farms LLC, it’s not available to use if any of the following are found:

  • The Petoskey Farms LLC
  • A Petoskey Farm Inc.
  • Petoskey and Farms L.L.C.
  • Petoskey & Farms Corp


Differences in capitalization don’t create distinguishability.

If your desired LLC name is Lake Iris Florist LLC, it’s not available to use if any of the following are found:

  • lake iris florist Inc.
  • LAKE IRIS Florist LP
  • LaKe iRiS fLoRiSt, LLC

Said another way, you’re allowed to use any capitalization you want. It just doesn’t make your name distinguishable from an existing company with the same name.

Exception: Plural or Singular Words

In Michigan, plural or singular words make a business name distinguishable.

If your desired LLC name is Big Pine Sled Company LLC, it is still available to use even if you find the following in the business name search results:

  • Big Pines Sled Company LLC
  • Big Pine Sleds Company LLC
  • Big Pines Sleds Company LLC

What if my Michigan business name is unavailable?

If you file your Michigan LLC Articles of Organization (the document that creates your Michigan LLC) and the business name is not available, don’t panic. The state will notify you and tell you why your filing was rejected.

You will just need to file again with a variation of your LLC name or a different LLC name. If you re-file your Articles of Organization within 60 days, you won’t have to pay the state fee again.

Michigan Business Name FAQs

Does my Michigan LLC need a DBA?

No, you’re not required to file a DBA (“Doing Business As”) for your LLC in Michigan.

A DBA (also known as an Assumed Name in Michigan) lets your LLC conduct business under a name which is different from its true and legal name (the name on your Articles of Organization).

If you want your LLC to do business under a name that’s different from its true and legal name, you have to file a Certificate of Assumed Name with the Michigan Department of Licensing and Regulatory Affairs (LARA). You can file the Assumed Name application online or by mail (mail filings are easier). The fee is $25 and your Michigan DBA needs to be renewed every 5 years.

If you are going to file a DBA for your Michigan business, it must also be distinguishable from the names of existing businesses in the state.

There is no limit to the number of DBAs an LLC can have.

For more information, please see Does my LLC need a DBA?

When would my LLC use a DBA?

Let’s say you form an LLC called Brandi’s Hair Salon LLC, but you also want a friendlier, catchy name, like Brandi’s Braids. In this case, your LLC would need to file a Certificate of Assumed Name to use the name Brandi’s Braids.

Similarly, if you want to do business under the name Brandi’s Hair Salon, just without the letters “LLC” in the name, you will need to file a DBA for Brandi’s Hair Salon.

How do I get a business domain name?

Once you’ve found a business name that you like, it’s a good idea to check if the domain name is available before forming your LLC.

You can search for your domain name with GoDaddy:

What does “distinguishability” mean?

Business entity names must be “distinguishable upon the records” of the Secretary of State.

This means that no two businesses can operate with the same exact name. Said another way, if a business already exists with your desired LLC name, you can’t register your LLC with that name.

For example, let’s say you want to form an LLC called Mastodon Music Lessons LLC. But there is already a business in another town called Mastodon Music Lessons, Inc. Because your desired LLC name is the same as that existing Michigan Corporation, it is not distinguishable. You can’t use it and must choose another name.

How do I come up with a business name?

The name of your Michigan LLC can be your company’s brand name, but it doesn’t have to be (please see the DBA section above). Either way, picking a good LLC name is an important decision.

Here are some quick tips:

  1. First, write down the features of your company and things that you want to be associated with.
  2. Then list out as many business names as you can think of. Don’t edit or analyze them. Just get as many names on the page as you can.
  3. Now go back and read through them. Write down any variations that come to mind.
  4. Next, set the list aside. Do something else, like go for a walk or get groceries, or sleep on it for the night. Then come back and review the list of names. As you go through it, write down additional ideas and variations.
  5. Read the whole list out loud. If you want, get input from friends, business partners, and family.
  6. Repeat the process: sleep on the ideas, write down new variations, read them out loud again.
  7. The best business name will often “rise off the page” and present itself. If it doesn’t, you can try this trick: Close your eyes and count to 10. When you get to 10, you must choose a name. When you open your eyes, force yourself to make a decision. Sometimes we know the best name deep in our subconscious, and this trick can help it come out. Trust yourself and go with what feels best.

Do I need a name reservation in Michigan?

No, a name reservation isn’t required to form an LLC in Michigan. It’s an unnecessary step and a waste of money.

You can just file your LLC’s Articles of Organization with your desired LLC name.

Can I use the name of another Michigan entity?

No. You can’t use the same name as another Michigan business.

And it doesn’t matter what entity type it is – your LLC can’t have the same entity name as another corporation, LLC, or any other entity type.

You can’t use another business’s name even if the entity is in “delinquent” status on the Michigan LARA website.

But if a business is dissolved, they no longer have rights to that name. This means you can form an LLC with the same name.

How to start an LLC in Michigan?

Here are the steps to starting an LLC in Michigan:

  1. Choose an LLC name and make sure it’s available
  2. Choose who will be your Michigan Registered Agent
  3. File the Michigan LLC Articles of Organization
  4. Complete and sign an LLC Operating Agreement
  5. Get a Tax ID Number (EIN) from the IRS
  6. Open an LLC bank account
  7. Check whether you need a business or sales tax license in Michigan

  1. Hell o Matt, I just stumble upon your site and you have awesome information here. I’m in the process of trying to establish my business. I’m going to follow your instructions to the “T”. Thank you for all that you do !

    Go Dragons !!

    • Hi Hussam, the link is working, but it must be visited from a computer in the US. If you’re outside of the US, you’ll need to use a proxy web search to access the link. Hope that helps.

  2. The link to the Michigan state business entity (LLC) lookup is broken. Tried calling them and they route you to their corporate office, which gives you a message that because their phone system is screwed up, they can’t accept calls. What kind of business model is this? GOVERNMENT!

    • Hi Ken, the link hasn’t changed, but it’s working now (it was down for a bit). I hear your concern, and the Michigan Secretary of State is in the process of rolling out new website changes, as well as internal changes to their telephone systems. It be a few weeks before all the kinks are ironed out. But overall, the Michigan Secretary of State (and the LARA office) are very helpful. We just need a little patience as they roll out their new and improved systems. Hope that helps :)

  3. Great information!!
    Is it advisable to simply use your name in your LLC such as:
    John H. Doe, LLC?

    • Hey Mike, thanks! Using your name in your LLC is a personal preference. You can certainly can, but you don’t have to. If your name is closely attached to your brand, then it may be a good idea. Other people prefer more privacy, although, by the nature of your question, it doesn’t sound like this is a concern. Another thing to think about is avoiding confusion: not letting people mistake your LLC from you as an individual. Hope that helps a bit. Let me know if you have any followup questions.
